and a perforated plate below said cover to reston stock beingdyed, to prevent channeling. More specifically, the invention relates to an apparatus similar to that disclosed in the F. M. Morton, U.`S. Patent No. 1,737,940, of December 3, 1929,\in which vthe perforated plate is so con- ,K nected'with the cover that said cover can move further down to closed position after the plate initially rests von the stock, the plate can vertically move with any vertical movements of the rstock during dyeing, and removal of the cover will alsol 'effect removal of the plate. g' The principal` object'of the invention is to provide an improved sliding connection between the platek 4and the cover having no parts projecting downwardly from said plate with danger of catching in the stock. Another object is to provide an exceptionally simple and inexpensive construction, yet one which will be effective and durable.

With the foregoing in view, the invention resides in'the novel subject matter hereinafter described and claimed, description being accomplished byreference to the accompanying drawmg.

Figure l is a top planview of a dye vat and its cover, equipped with the invention.

2 2 of Fig. 1.

Figure 3 is a disassembled sectional view showing the improved connecting means.

A preferred construction has been illustrated and will be `rather specifically described, with the understanding, however, that within the scope of thel invention as claimed, variations may be made.

A cover 5 is shown` `for a vat 6, and clamps I have been illustratedv for securing ysaid cover in closed position. The cover 5 in the present disclosure is provided with, an inlet 8 for the dye liquor, and an outlet 9 is provided from the bottom` of Athe vat beneath a perforated falsev Figure 2 is a vertical sectional view on line (c1. ca -187) with a continuous lateral ange I5 secured upon said cover by cap screws or the like I6, the upper end of said cylinder being closed by a suitable plate Il which may be secured in place by screws or the like I8. The lower end wall I9 of the 5 cylinder I3 is formed with an opening 20 through which a vertical stem 2| passes slidably, said stem being rigidly secured to the perforated plate II andv having a head 22 slidable in the cylinder I3, said head projecting laterally in all 10 directions fromr saidstem. In securing the stem 2| to the plate II, I provide the lower end oi said stem lwith a reduced portion 23, pass this portion through an opening 24 in the plate, and thread a nut 25 on said reduced vportion in con- 15 tact with the lower side of said plate. The entire stem can thus move vertically with the plat-e II, downward movement ofl this plate being limited by the head 22 striking the lower end wall t I9 of the cylinder I3, whereas upward movement 29 of said plate is limited by striking of said end wall against said plate.

By providing the novel construction shown and described, the objects of the invention are readily attained, particular attention being invited g5 to the fact that the novel connecting means between the cover and the plate possesses no downwardly projecting portions to become entangled in the stock.

As excellent results may be obtained from the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, variations may, of course, be made.

I claim: f

1. In a dyeing apparatus having a vat cover and a perforated plate under said cover to rest on stockbeing dyed; connecting means between said plate and cover comprising a hollow vertical cylinder secured to said cover and having upper and lower end walls, said lower end wall being formed with an opening, and a stem secured to and projecting upwardly from said plate, said stem passing slidably through said opening and having a laterally projecting portion slidable in said cylinder, said laterally pro- 5 jecting portion being disposed in position to rest upon said lower end wall of said cylinderA when said perforated plate occupies its lowest position with respectto said vat cover.

2. In a dyeing apparatus having a vat cover and a perforated plate under said cover to rest on the stock being dyed; connecting means between said plate and cover comprising a hollow vertical cylinder extending through an opening in said cover and having a lateral flange seu cured to the latter, said cylinder having upper and lower end walls, the latter of which is formed with an opening, and a stem secured to and projecting upwardly from said plate, said stem passing slidably through said opening and having a laterally projecting portion slidable in said cylinder, said laterally projecting portion being disposed in position to rest upon said lower end wall of said cylinder when said perforated plate occupies its lowest positionnwith respect to said vat cover.
